JAR-CLOSURE.

Application filed December 22, 1919.

To all whom it may concern:

Be it known that I, WILLIAM F. Krrr, a citizen of the United States, residing at Fort Lupton, in the county of Weld and State of Colorado, have invented certain new and useful Improvements in J ar-Closures, of which the following is a specification.

This invention relates to closures, and the primary object of the invention is to providean improved closure for preserve jars and the like, which will effectively seal the jars and prevent entrance of air into the same and hold the fruit or the like immersed in the syrup.

Another object of the invention is to provide an improved closure for preserve jars includinga clamp arranged to engage the jar and having adjustable means for engaging the closure to firmly hold the same in sealing contact with the jar.

A further object of the invention is the provision of an improved jar closure embodying a depressed portion arranged to fit within the jar neck for holding the fruit in its preserving syrup, said depressed portion being adapted to receive the adjustable means carried by the locking clamp for holding the closure in tight engagement with the jar neck.

A further object of the invention is to provide an improved clamp for engaging jar closures, which is durable and efficient in use, i one that 1s simple and easy to manufacture,

and one which can be placed upon the market at a reasonable cost.

Other objects of the invention will appear in the following detailed description taken in connection with the drawings, forming a part of this specification and in which drawin s:

Tigure 1 is a vertical section through a jar neck and closure.

Fig. 2 is a plan view of the same.

Referring to the drawings, in detail, wherein similar reference characters designate corresponding parts throughout the several views the letter A indicates a closure for the jar neck B and C indicates the improved clamp for holding the closure in tight engagement with the jar neck.

The jar neck is preferably formed of glass or other vitreous material and is provided with a wide mouth so as to permit the ready cleaning thereof and the placing of large pieces of fruit into the same. The jar is provided intermediate its ends with an annular Specification of Letters Patent.

flange 5 which is undercut as at 6 for a purpose which will be hereinafter more fully described. The cover or closure A is also preferably formed of glass or other vitreous material and includes a centrally disposed inverted hollow frusto-conical body 7havinga thickened lower wall 8 provided with a socket 9 formed in its upper face. The inclined wall 10 of the frusto-conical body 7 is provided with an outwardly extending annular flange 11, which is adapted to engage the upper edge of the neck B of the jar. A gasket formed of rubber or the like is adapted to be interposed between the flange 11 and the jar neck. If so desired the flange 11 may be provided with a depending right angular extending annular extension 13 which is spaced sufficient distance from the inside wall 10 of the frusto-conical bodyso as to snugly engage the outer surface of the jar neck The clamp C includes a circular flat body 14:, which is adapted to be received in the hollow frusto-conical body 7 and the same is provided with upwardly extending outwardly inclined radially disposed legs 15 at equidistantly spaced points. The legs 15 are provided with outwardly extending shoulders 16, which are adapted to engage or overlie the upper surface of the annular flange 11 formed on the inclined wall 10 of the closure. The legs 15 and the angular terminals 16 and the disk or body 14 are provided with up wardly extending right angularly disposed guard flanges 17 which brace the legs and circular body and prevent movement thereof. The outer terminals of the angularly extending extensions 16 are provided with depending flexible arms 18 which are provided with hooked ends 19 which are adapted to engage under theundercut face 6 of the annular retaining flange 5 formed on the jar neck B.

The central portion of a disk or plate 14 is provided with an enlarged center or hub 20 which is provided with internal threads arranged to receive the set screw 21, the lower end of which is provided with a rounded. bearing face 22 arranged to engage in the socket 9. In. use of the improved jar, the fruits, vegetables or the like are placed in the jar and the closure A is placed in the neck B, which will press the fruit, vegetables or the like down into the body of the jar, and owing to the shape of the closure, the preserving liquid will ride upward in rmediate the closure and the inner surface of the jar neck. After the closure A has been placed in position, the clamp C is brought into engage ment with the closure and over the jar neck. The arms 18 are sprung outward and the hooked ends are brought into engagement with the annular flange 5. The screw 21 is then threaded downwardly, which will lift up on the clam B and have atendency to stretch the downwardly extending armslS,

, thus forcing the closure A into intimate contact with the gasket 12. The construction of the clamp C is such that the jars may be readily inverted and immersed in hot or cold water during the canning process, and the flanges 17 will hold the jar above the bottom of the kettle and permit the circulation of wall thereof, the upper ends of the body portion having outwardly extending flanges arranged to engage the upper edge of the jar neck, and means for holding the flanges in engagement with the upper edge of the jar neck having the major portion thereof located below the plane of the upper edge of the closure. p

2. The combination with a jar neck, of a closure therefor including an imperforated frusto conical body portion arranged to extend in the jar neck in spaced relation to the. side wall thereof, an outwardly extending annular flange formed on the upper edge of the frusto-conical body and arranged to engage the upper edge of the jar neck, and adjustable means arranged to engage the jar neck and closure to hold the flange in tight contact with the upper edge ofthe jar neck.

The combination with a jar neck including an annular outwardly extending flange, of a closure for the neck including a body arranged to extend into the neck and having an outwardly extending annular flange arranged to engagethe upper edge of the ar neck,sa clamp including a disk shaped body arranged to extend in the body of the jar closure, upwardly extending rigid legs formed on the disk, and depending flexible arms formed on the legs arranged to engage the annular flange, and adjustable means carried by the clamp body for engagement with the body of the closure and arranged to extend within the plane of the upper edge of the closure.

4; The combination with a jar neck including an annular outwardly extending flange having an undercut lower face, of a closure'for the jar neck including a hollow frusto conical body arranged to extend into the. jar neck and having an outwardly extending annular flange arranged to engage the upper edge of the jar neck, said flange being provided with a depending right angular extension, and a clamp including a circular body arranged to fit in the hollow frusto conical body of the closure, upstanding legs formed on the circular body, said legs having outwardly extending extensions provided with outwardly extending guard flanges, depending resilient arms formed on the terminals of the legs, said arms having hooked terminals arranged to engage the undercut portion of the annular flange formed on the neck, and a set screw carried by the circular plate and arranged to engage the body of the closure and lie within the planeof the upper edge of the body of the closure. g I v 5. A clamp for ar closures including a circular body, outwardly extending upwardly directed legs formed on the circular body, angular extending horizontally disposed extensions formed on said. body legs, the edges of the legs and extensions being provided with upstanding bracing flanges, and flexible depending arms formed on the legs arranged to extend below the circular body.
